How To Operate A Folding Ladder

How to operate a folding ladder

(Two fold ladder and four fold ladder)

1. Lock and unfold the ladder pillar outward. When you hear a "click" sound and the lock block enters the position, it indicates that the hinge has locked this position.

2. Open the lock by pulling the handle, and at the same time, the lock block is retracted to the position, indicating that the hinge has been unlocked. At this time, the angle between the ladder pillars can be changed or the ladder can be folded

*If you encounter a situation where the handle cannot be pulled and the lock cannot be opened, it is because the hinge is under pressure on the lock block. At this time, you can pull the ladder pillar and shake it to release the external force

3. After checking that the ladder is in use, please carefully confirm that all hinges are in the locked position before use. If there are hinges with lock blocks in position, they can be symmetrically opened, then retract the ladder pillar inward by about 40 degrees, and then unfold outward to lock the pair of hinges

4. Attention:

a. A ladder with a total length of less than or equal to 4 meters can be unfolded into a straight ladder for use. At this time, the angle between the ladder and the ground should be greater than 75 degrees, and the hinge in the middle of the ladder should face the wall

b. When using a four fold ladder as a platform, it is necessary to pad a flat plate with a thickness of at least 1cm

c. When someone is working on a ladder, it is strictly prohibited for others to pull the handle to change the locking status of the hinges
